The Vâlsan is a left tributary of the river Argeș in Romania.[1][2] It discharges into the Argeș near Merișani.[3] Its length is 79 km (49 mi) and its basin size is 348 km² (134 sq mi).[2]

The Vâlsan originates in the Făgăraș Mountains, where its source is a trough-shaped glacial hollow located between the Picuiata and Scărișoara Mare mountains. The river flows for a mere 84.6 kilometers. Its course runs parallel to the Argeș River. The Vâlsan River's mouth is located at Merișani.[4]

In 1967 the Vâlsan's course was altered significantly by the construction of a reservoir and a hydroelectric plant.[4]

Tributaries

The following rivers are tributaries to the river Vâlsan (from source to mouth):[2]

Right tributaries: Izvorul Dimei, Izvorul Popii, Robaia, Valea Părului, Șoptana, Toplița, Bunești

Haven for a Fish Species

The Vâlsan, although a minor river in comparison to other European rivers, is of vital importance. This is because it is one of the few rivers that supports the fish species Romanichthys valsanicola. This species is endemic to Romania and the Danube basin. The species is regarded the most endangered species of European ichthyofauna given its small habitat range and low surviving numbers.[4]
